block: fix lost bio for plug enabled bio based device
With the following two conditions, bio will be lost:
1) blk plug is not enabled, for example, __blkdev_direct_IO_simple() and
__blkdev_direct_IO_async();
2) bio plug is enabled, for example write IO for raid1/raid10 while
bitmap is enabled;
Root cause is that blk_finish_plug() will add the bio to
curent->bio_list, while such bio will not be handled:
__submit_bio_noacct
current->bio_list = bio_list_on_stack;
blk_start_plug
do {
dm_submit_bio
md_handle_request
raid10_write_request
-> generate new bio for underlying disks
raid1_add_bio_to_plug -> bio is added to plug
} while ((bio = bio_list_pop(&bio_list_on_stack[0])))
-> previous bio are all handled
blk_finish_plug
raid10_unplug
raid1_submit_write
submit_bio_noacct
if (current->bio_list)
bio_list_add(¤t->bio_list[0], bio)
-> add new bio
current->bio_list = NULL
-> new bio is lost
Fix the problem by moving the plug into the while loop, so that
current->bio_list will still be handled after blk_finish_plug().
By the way, enable plug for raid1/raid10 in this case will also prevent
delay IO handling into daemon thread, which should also improve IO
performance.

ring-buffer: Fix a race between readers and resize checks
The reader code in rb_get_reader_page() swaps a new reader page into the ring buffer by doing cmpxchg on old->list.prev->next to point it to the new page. Following that, if the operation is successful, old->list.next->prev gets updated too. This means the underlying doubly-linked list is temporarily inconsistent, page->prev->next or page->next->prev might not be equal back to page for some page in the ring buffer. The resize operation in ring_buffer_resize() can be invoked in parallel. It calls rb_check_pages() which can detect the described inconsistency and stop further tracing: [ 190.271762] ------------[ cut here ]------------ [ 190.271771] WARNING: CPU: 1 PID: 6186 at kernel/trace/ring_buffer.c:1467 rb_check_pages.isra.0+0x6a/0xa0 [ 190.271789] Modules linked in: [...] [ 190.271991] Unloaded tainted modules: intel_uncore_frequency(E):1 skx_edac(E):1 [ 190.272002] CPU: 1 PID: 6186 Comm: cmd.sh Kdump: loaded Tainted: G E 6.9.0-rc6-default #5 158d3e1e6d0b091c34c3b96bfd99a1c58306d79f [ 190.272011] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.16.0-0-gd239552c-rebuilt.opensuse.org 04/01/2014 [ 190.272015] RIP: 0010:rb_check_pages.isra.0+0x6a/0xa0 [ 190.272023] Code: [...] [ 190.272028] RSP: 0018:ffff9c37463abb70 EFLAGS: 00010206 [ 190.272034] RAX: ffff8eba04b6cb80 RBX: 0000000000000007 RCX: ffff8eba01f13d80 [ 190.272038] RDX: ffff8eba01f130c0 RSI: ffff8eba04b6cd00 RDI: ffff8eba0004c700 [ 190.272042] RBP: ffff8eba0004c700 R08: 0000000000010002 R09: 0000000000000000 [ 190.272045] R10: 00000000ffff7f52 R11: ffff8eba7f600000 R12: ffff8eba0004c720 [ 190.272049] R13: ffff8eba00223a00 R14: 0000000000000008 R15: ffff8eba067a8000 [ 190.272053] FS: 00007f1bd64752c0(0000) GS:ffff8eba7f680000(0000) knlGS:0000000000000000 [ 190.272057] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 190.272061] CR2: 00007f1bd6662590 CR3: 000000010291e001 CR4: 0000000000370ef0 [ 190.272070] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 190.272073] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ 190.272077] Call Trace: [ 190.272098] <TASK> [ 190.272189] ring_buffer_resize+0x2ab/0x460 [ 190.272199] __tracing_resize_ring_buffer.part.0+0x23/0xa0 [ 190.272206] tracing_resize_ring_buffer+0x65/0x90 [ 190.272216] tracing_entries_write+0x74/0xc0 [ 190.272225] vfs_write+0xf5/0x420 [ 190.272248] ksys_write+0x67/0xe0 [ 190.272256] do_syscall_64+0x82/0x170 [ 190.272363] entry_SYSCALL_64_after_hwframe+0x76/0x7e [ 190.272373] RIP: 0033:0x7f1bd657d263 [ 190.272381] Code: [...] [ 190.272385] RSP: 002b:00007ffe72b643f8 EFLAGS: 00000246 ORIG_RAX: 0000000000000001 [ 190.272391] RAX: ffffffffffffffda RBX: 0000000000000002 RCX: 00007f1bd657d263 [ 190.272395] RDX: 0000000000000002 RSI: 0000555a6eb538e0 RDI: 0000000000000001 [ 190.272398] RBP: 0000555a6eb538e0 R08: 000000000000000a R09: 0000000000000000 [ 190.272401] R10: 0000555a6eb55190 R11: 0000000000000246 R12: 00007f1bd6662500 [ 190.272404] R13: 0000000000000002 R14: 00007f1bd6667c00 R15: 0000000000000002 [ 190.272412] </TASK> [ 190.272414] ---[ end trace 0000000000000000 ]--- Note that ring_buffer_resize() calls rb_check_pages() only if the parent trace_buffer has recording disabled.

perf tools fixes and improvements for v6.10:
- Add Kan Liang to MAINTAINERS as a perf tools reviewer. - Add support for using the 'capstone' disassembler library in various tools, such as 'perf script' and 'perf annotate'. This is an alternative for the use of the 'xed' and 'objdump' disassemblers. - Data-type profiling improvements: Resolve types for a->b->c by backtracking the assignments until it finds DWARF info for one of those members Support for global variables, keeping a cache to speed up lookups. Handle the 'call' instruction, dealing with effects on registers and handling its return when tracking register data types. Handle x86's segment based addressing like %gs:0x28, to support things like per CPU variables, the stack canary, etc. Data-type profiling got big speedups when using capstone for disassembling. The objdump outoput parsing method is left as a fallback when capstone fails or isn't available. There are patches posted for 6.11 that to use a LLVM disassembler. Support event group display in the TUI when annotating types with --data-type, for instance to show memory load and store events for the data type fields. Optimize the 'perf annotate' data structures, reducing memory usage. Add a initial 'perf test' for 'perf annotate', checking that a target symbol appears on the output, specifying objdump via the command line, etc. - Integrate the shellcheck utility with the build of perf to allow catching shell problems early in areas such as 'perf test', 'perf trace' scrape scripts, etc. - Add 'uretprobe' variant in the 'perf bench uprobe' tool. - Add script to run instances of 'perf script' in parallel. - Allow parsing tracepoint names that start with digits, such as 9p/9p_client_req, etc. Make sure 'perf test' tests it even on systems where those tracepoints aren't available. Vendor Events: - Update Intel JSON files for Cascade Lake X, Emerald Rapids, Grand Ridge, Ice Lake X, Lunar Lake, Meteor Lake, Sapphire Rapids, Sierra Forest, Sky Lake X, Sky Lake and Snow Ridge X. Remove info metrics erroneously in TopdownL1. - Add AMD's Zen 5 core and uncore events and metrics. Those come from the "Performance Monitor Counters for AMD Family 1Ah Model 00h- 0Fh Processors" document, with events that capture information on op dispatch, execution and retirement, branch prediction, L1 and L2 cache activity, TLB activity, etc. - Mark L1D_CACHE_INVAL impacted by errata for ARM64's AmpereOne/AmpereOneX. Miscellaneous: - Sync header copies with the kernel sources. - Move some header copies used only for generating translation string tables for ioctl cmds and other syscall integer arguments to a new directory under tools/perf/beauty/, to separate from copies in tools/include/ that are used to build the tools. - Introduce scrape script for several syscall 'flags'/'mask' arguments. - Improve cpumap utilization, fixing up pairing of refcounts, using the right iterators (perf_cpu_map__for_each_cpu), etc. - Give more details about raw event encodings in 'perf list', show tracepoint encoding in the detailed output. - Refactor the DSOs handling code, reducing memory usage. - Document the BPF event modifier and add a 'perf test' for it. - Improve the event parser, better error messages and add further 'perf test's for it. - Add reference count checking to 'struct comm_str' and 'struct mem_info'. - Make ARM64's 'perf test' entries for the Neoverse N1 more robust. - Tweak the ARM64's Coresight 'perf test's. - Improve ARM64's CoreSight ETM version detection and error reporting. - Fix handling of symbols when using kcore. - Fix PAI (Processor Activity Instrumentation) counter names for s390 virtual machines in 'perf report'. - Fix -g/--call-graph option failure in 'perf sched timehist'. - Add LIBTRACEEVENT_DIR build option to allow building with libtraceevent installed in non-standard directories, such as when doing cross builds. - Various 'perf test' and 'perf bench' fixes. - Improve 'perf probe' error message for long C++ probe names.

io_uring/sqpoll: ensure that normal task_work is also run timely
With the move to private task_work, SQPOLL neglected to also run the
normal task_work, if any is pending. This will eventually get run, but
we should run it with the private task_work to ensure that things like
a final fput() is processed in a timely fashion.

more s390 updates for 6.10 merge window
- Switch read and write software bits for PUDs - Add missing hardware bits for PUDs and PMDs - Generate unwind information for C modules to fix GDB unwind error for vDSO functions - Create .build-id links for unstripped vDSO files to enable vDSO debugging with symbols - Use standard stack frame layout for vDSO generated stack frames to manually walk stack frames without DWARF information - Rework perf_callchain_user() and arch_stack_walk_user() functions to reduce code duplication - Skip first stack frame when walking user stack - Add basic checks to identify invalid instruction pointers when walking stack frames - Introduce and use struct stack_frame_vdso_wrapper within vDSO user wrapper code to automatically generate an asm-offset define. Also use STACK_FRAME_USER_OVERHEAD instead of STACK_FRAME_OVERHEAD to document that the code works with user space stack - Clear the backchain of the extra stack frame added by the vDSO user wrapper code. This allows the user stack walker to detect and skip the non-standard stack frame. Without this an incorrect instruction pointer would be added to stack traces. - Rewrite psw_idle() function in C to ease maintenance and further enhancements - Remove get_vtimer() function and use get_cpu_timer() instead - Mark psw variable in __load_psw_mask() as __unitialized to avoid superfluous clearing of PSW - Remove obsolete and superfluous comment about removed TIF_FPU flag - Replace memzero_explicit() and kfree() with kfree_sensitive() to fix warnings reported by Coccinelle - Wipe sensitive data and all copies of protected- or secure-keys from stack when an IOCTL fails - Both do_airq_interrupt() and do_io_interrupt() functions set CIF_NOHZ_DELAY flag.

arm64: asm-bug: Add .align 2 to the end of __BUG_ENTRY
When CONFIG_DEBUG_BUGVERBOSE=n, we fail to add necessary padding bytes
to bug_table entries, and as a result the last entry in a bug table will
be ignored, potentially leading to an unexpected panic(). All prior
entries in the table will be handled correctly.
The arm64 ABI requires that struct fields of up to 8 bytes are
naturally-aligned, with padding added within a struct such that struct
are suitably aligned within arrays.
When CONFIG_DEBUG_BUGVERPOSE=y, the layout of a bug_entry is:
struct bug_entry {
signed int bug_addr_disp; // 4 bytes
signed int file_disp; // 4 bytes
unsigned short line; // 2 bytes
unsigned short flags; // 2 bytes
}
... with 12 bytes total, requiring 4-byte alignment.
When CONFIG_DEBUG_BUGVERBOSE=n, the layout of a bug_entry is:
struct bug_entry {
signed int bug_addr_disp; // 4 bytes
unsigned short flags; // 2 bytes
< implicit padding > // 2 bytes
}
... with 8 bytes total, with 6 bytes of data and 2 bytes of trailing
padding, requiring 4-byte alginment.
When we create a bug_entry in assembly, we align the start of the entry
to 4 bytes, which implicitly handles padding for any prior entries.
However, we do not align the end of the entry, and so when
CONFIG_DEBUG_BUGVERBOSE=n, the final entry lacks the trailing padding
bytes.
For the main kernel image this is not a problem as find_bug() doesn't
depend on the trailing padding bytes when searching for entries:
for (bug = __start___bug_table; bug < __stop___bug_table; ++bug)
if (bugaddr == bug_addr(bug))
return bug;
However for modules, module_bug_finalize() depends on the trailing
bytes when calculating the number of entries:
mod->num_bugs = sechdrs[i].sh_size / sizeof(struct bug_entry);
... and as the last bug_entry lacks the necessary padding bytes, this entry
will not be counted, e.g. in the case of a single entry:
sechdrs[i].sh_size == 6
sizeof(struct bug_entry) == 8;
sechdrs[i].sh_size / sizeof(struct bug_entry) == 0;
Consequently module_find_bug() will miss the last bug_entry when it does:
for (i = 0; i < mod->num_bugs; ++i, ++bug)
if (bugaddr == bug_addr(bug))
goto out;
... which can lead to a kenrel panic due to an unhandled bug.
This can be demonstrated with the following module:
static int __init buginit(void)
{
WARN(1, "hello\n");
return 0;
}
static void __exit bugexit(void)
{
}
module_init(buginit);
module_exit(bugexit);
MODULE_LICENSE("GPL");
... which will trigger a kernel panic when loaded:

Hi,
These are couple of bugs I found from trusted keys while working on a new asymmetric key type for TPM2 [1]. Both originate form v5.13.

gpiolib: acpi: Fix failed in acpi_gpiochip_find() by adding parent node match
Previous patch modified the standard used by acpi_gpiochip_find() to match device nodes. Using the device node set in gc->gpiodev->d- ev instead of gc->parent. However, there is a situation in gpio-dwapb where the GPIO device driver will set gc->fwnode for each port corresponding to a child node under a GPIO device, so gc->gpiodev->dev will be assigned the value of each child node in gpiochip_add_data(). gpio-dwapb.c: 128,31 static int dwapb_gpio_add_port(struct dwapb_gpio *gpio, struct dwapb_port_property *pp, unsigned int offs); port->gc.fwnode = pp->fwnode; 693,39 static int dwapb_gpio_probe; err = dwapb_gpio_add_port(gpio, &pdata->properties[i], i); When other drivers request GPIO pin resources through the GPIO device node provided by ACPI (corresponding to the parent node), the change of the matching object to gc->gpiodev->dev in acpi_gpiochip_find() only allows finding the value of each port (child node), resulting in a failed request. Reapply the condition of using gc->parent for match in acpi_gpio- chip_find() in the code can compatible with the problem of gpio-dwapb, and will not affect the two cases mentioned in the patch: 1. There is no setting for gc->fwnode. 2. The case that depends on using gc->fwnode for match. Fixes: |

openvswitch: Set the skbuff pkt_type for proper pmtud support.
Open vSwitch is originally intended to switch at layer 2, only dealing with
Ethernet frames. With the introduction of l3 tunnels support, it crossed
into the realm of needing to care a bit about some routing details when
making forwarding decisions. If an oversized packet would need to be
fragmented during this forwarding decision, there is a chance for pmtu
to get involved and generate a routing exception. This is gated by the
skbuff->pkt_type field.
When a flow is already loaded into the openvswitch module this field is
set up and transitioned properly as a packet moves from one port to
another. In the case that a packet execute is invoked after a flow is
newly installed this field is not properly initialized. This causes the
pmtud mechanism to omit sending the required exception messages across
the tunnel boundary and a second attempt needs to be made to make sure
that the routing exception is properly setup. To fix this, we set the
outgoing packet's pkt_type to PACKET_OUTGOING, since it can only get
to the openvswitch module via a port device or packet command.
Even for bridge ports as users, the pkt_type needs to be reset when
doing the transmit as the packet is truly outgoing and routing needs
to get involved post packet transformations, in the case of
VXLAN/GENEVE/udp-tunnel packets. In general, the pkt_type on output
gets ignored, since we go straight to the driver, but in the case of
tunnel ports they go through IP routing layer.
This issue is periodically encountered in complex setups, such as large
openshift deployments, where multiple sets of tunnel traversal occurs.
A way to recreate this is with the ovn-heater project that can setup
a networking environment which mimics such large deployments. We need
larger environments for this because we need to ensure that flow
misses occur. In these environment, without this patch, we can see:
./ovn_cluster.sh start
podman exec ovn-chassis-1 ip r a 170.168.0.5/32 dev eth1 mtu 1200
podman exec ovn-chassis-1 ip netns exec sw01p1 ip r flush cache
podman exec ovn-chassis-1 ip netns exec sw01p1 \
ping 21.0.0.3 -M do -s 1300 -c2
PING 21.0.0.3 (21.0.0.3) 1300(1328) bytes of data.
From 21.0.0.3 icmp_seq=2 Frag needed and DF set (mtu = 1142)
--- 21.0.0.3 ping statistics ---
...
Using tcpdump, we can also see the expected ICMP FRAG_NEEDED message is not
sent into the server.
With this patch, setting the pkt_type, we see the following:
podman exec ovn-chassis-1 ip netns exec sw01p1 \
ping 21.0.0.3 -M do -s 1300 -c2
PING 21.0.0.3 (21.0.0.3) 1300(1328) bytes of data.
From 21.0.0.3 icmp_seq=1 Frag needed and DF set (mtu = 1222)
ping: local error: message too long, mtu=1222
--- 21.0.0.3 ping statistics ---
...
In this case, the first ping request receives the FRAG_NEEDED message and
a local routing exception is created.

af_unix: Fix garbage collection of embryos carrying OOB with SCM_RIGHTS
GC attempts to explicitly drop oob_skb's reference before purging the hit
list.
The problem is with embryos: kfree_skb(u->oob_skb) is never called on an
embryo socket.
The python script below [0] sends a listener's fd to its embryo as OOB
data. While GC does collect the embryo's queue, it fails to drop the OOB
skb's refcount. The skb which was in embryo's receive queue stays as
unix_sk(sk)->oob_skb and keeps the listener's refcount [1].
Tell GC to dispose embryo's oob_skb.

regulator: tps6594-regulator: Correct multi-phase configuration
According to the TPS6594 PMIC Manual (linked) 8.3.2.1.4 Multi-Phase BUCK
Regulator Configurations section, the PMIC ignores all the other bucks'
except the primary buck's regulator registers. This is BUCK1 for
configurations BUCK12, BUCK123 and BUCK1234 while it is BUCK3 for
BUCK34. Correct the registers mapped for these configurations
accordingly.

selftests/net: use tc rule to filter the na packet
Test arp_ndisc_untracked_subnets use tcpdump to filter the unsolicited
and untracked na messages. It set -e before calling tcpdump. But if
tcpdump filters 0 packet, it will return none zero, and cause the script
to exit.
Instead of using slow tcpdump to capture packets, let's using tc rule
to filter out the na message.
At the same time, fix function setup_v6 which only needs one parameter.
Move all the related helpers from forwarding lib.sh to net lib.sh.

ipv6: sr: fix memleak in seg6_hmac_init_algo
seg6_hmac_init_algo returns without cleaning up the previous allocations
if one fails, so it's going to leak all that memory and the crypto tfms.
Update seg6_hmac_exit to only free the memory when allocated, so we can
reuse the code directly.

af_unix: Update unix_sk(sk)->oob_skb under sk_receive_queue lock.
Billy Jheng Bing-Jhong reported a race between __unix_gc() and
queue_oob().
__unix_gc() tries to garbage-collect close()d inflight sockets,
and then if the socket has MSG_OOB in unix_sk(sk)->oob_skb, GC
will drop the reference and set NULL to it locklessly.
However, the peer socket still can send MSG_OOB message and
queue_oob() can update unix_sk(sk)->oob_skb concurrently, leading
NULL pointer dereference. [0]
To fix the issue, let's update unix_sk(sk)->oob_skb under the
sk_receive_queue's lock and take it everywhere we touch oob_skb.
Note that we defer kfree_skb() in manage_oob() to silence lockdep
false-positive (See [1]).

KEYS: trusted: Do not use WARN when encode fails
When asn1_encode_sequence() fails, WARN is not the correct solution.
1. asn1_encode_sequence() is not an internal function (located
in lib/asn1_encode.c).
2. Location is known, which makes the stack trace useless.
3. Results a crash if panic_on_warn is set.
It is also noteworthy that the use of WARN is undocumented, and it
should be avoided unless there is a carefully considered rationale to
use it.
Replace WARN with pr_err, and print the return value instead, which is
only useful piece of information.
